"Genes in the somatic cells of the body undergo mutation with the passage of time. Such mutations cause senescence". This theory belongs to which type of theories for ageing?
1 Hormonal theory.
2 Programmed senescence theory.
3 Error and damage theories.
4 Immumological theories.
Explanation:
: Genes in the somatic cell of the body undergo nutation with passage of time. Such mutations cause senescence belongs to error and damage theory. Error and damage theories, emphasize environmental assaults to living organism that induce cumulative damage at warious lived as the cause of aging.

The formation of multivalent at meiosis in dipioid organism is due to
1 morosomy
2 deletion
3 inversion
4 reciprocal translocation
Explanation:
: The formation of multivalent during meiosis in diploid organisms can occur due to reciprocal translocations. Reciprocal translocations involve the exchange of genetic material between mon-homologous chromosomes, leacing to the presence of multivalent during meiosis, which can distupt normal chromosome segregation.

If mutation changes codon in such a way that there is no effect on functioning and overall structure of protein. This type of mutation is termed as
1 Silent
2 Mis sense
3 Transition
4 Frame shift
Explanation:
: Silent mutation is any gene mutation which bes not result in phenotyric expression. As more than one codon specify same amino acid (due to degeneracy of code). The change in codon may tot result into alteration in amino acid.

One of the parents of a cross has mutation in its mitochandria. In that cross, the parent is taken as male. During segregation of \(F_2\) progenies that mutation is found in
1 one thitd of progenies
2 None of the progenies
3 All of the progeries
4 half of the progenies
Explanation:
:Mitochondria of sperms are left behind during fertilization and hence the mitochondria of the progeny is completely of maternal origin. So, none of the progeries will be affected by the mutation. Mitochondrial genes show maternal inheritance. It means progenies get all the mitochondrial genes from the cytoplasm of the ovum or mother if there is any nutation in the mitochondria of male, it will not be found in any progeries of \(F_1\) generation.
